Mercedes-Benz Part 573 Submission
Original Submitted to Portal May 14, 2021
Chronology-Only section
Supplement to Original Submission

Chronology of Defect/Noncompliance Determination

In mid-July 2020, MBAG launched an investigation after receiving reports from the field describing situations where the rearview image in various vehicle platforms remained blank after the transmission was placed in reverse. The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other.

MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed.

Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation. While the reboot process was ongoing, the rearview image would be interrupted and would not be displayed, but would immediately reappear after the conclusion of the reboot process. MBAG further evaluated the length of the reboot process and it was found that while in many instances the reboot lasted for only one second or less, there was at least one instance where the reboot process lasted several seconds.

On May 7, 2021, MBAG determined that the vehicles do not meet the requirements of FMVSS 111 section 5 & 14 if either of the conditions were to occur and decided to conduct a non-compliance recall to address these issues.

The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other. MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed. Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation.

All customers will be mailed recall notification letters as required under federal regulations. For vehicles with a “Mercedes Me” subscription service, the software update will be performed OTA and so a dealer visit is not required. For vehicles without a Mercedes Me subscription service, the notification letter will advise the customer that they may opt out of the OTA update and visit an authorized Mercedes-Benz dealer to have the update performed. If the customer does not opt out within the specified period, the update will be performed OTA with the vehicle thereafter. Depending on conditions such as network coverage and consistency of the data connection, if the OTA update cannot be successfully completed, the customer will be notified and advised to visit an authorized dealer to have the update performed. Customers who subscribe to the Mercedes Me service may check the status of the update through the associated website and/or through the Mercedes Me App. If the vehicle is subscribed to the Mercedes Me Connect services, the current status of the remote software update will be listed on the Mercedes Me connect webpage under “Software Update”. Further information regarding software updates can be found in the Operator’s Manual.

The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other. MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed. Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation.

All customers will be mailed recall notification letters as required under federal regulations. For vehicles with a “Mercedes Me” subscription service, the software update will be performed OTA and so a dealer visit is not required. For vehicles without a Mercedes Me subscription service, the notification letter will advise the customer that they may opt out of the OTA update and visit an authorized Mercedes-Benz dealer to have the update performed. If the customer does not opt out within the specified period, the update will be performed OTA with the vehicle thereafter. Depending on conditions such as network coverage and consistency of the data connection, if the OTA update cannot be successfully completed, the customer will be notified and advised to visit an authorized dealer to have the update performed. Customers who subscribe to the Mercedes Me service may check the status of the update through the associated website and/or through the Mercedes Me App. If the vehicle is subscribed to the Mercedes Me Connect services, the current status of the remote software update will be listed on the Mercedes Me connect webpage under “Software Update”. Further information regarding software updates can be found in the Operator’s Manual.

The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it Part 573 Safety Recall Report 21V-354 Page 17 The information contained in this report was submitted pursuant to 49 CFR §573 would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other. MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed. Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation. Please see Chronology Supplement. Description of Remedy : Description of Remedy Program : Either an authorized Mercedes-Benz dealer or an over-the-air (“OTA”) update will update the communication module software for the MBUX system on the affected vehicles. All customers will be mailed recall notification letters as required under federal regulations. For vehicles with a “Mercedes Me” subscription service, the software update will be performed OTA and so a dealer visit is not required. For vehicles without a Mercedes Me subscription service, the notification letter will advise the customer that they may opt out of the OTA update and visit an authorized Mercedes-Benz dealer to have the update performed. If the customer does not opt out within the specified period, the update will be performed OTA with the vehicle thereafter. Depending on conditions such as network coverage and consistency of the data connection, if the OTA update cannot be successfully completed, the customer will be notified and advised to visit an authorized dealer to have the update performed. Customers who subscribe to the Mercedes Me service may check the status of the update through the associated website and/or through the Mercedes Me App. If the vehicle is subscribed to the Mercedes Me Connect services, the current status of the remote software update will be listed on the Mercedes Me connect webpage under “Software Update”. Further information regarding software updates can be found in the Operator’s Manual. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since the involved vehicles would not have been previously subject to the condition described. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since the involved vehicles would not have been previously subject to the condition described and all remain covered under the new vehicle warranty.

The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other. MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed. Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation.

Part 573 Safety Recall Report 21V-354 Page 17 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Either an authorized Mercedes-Benz dealer or an over-the-air (“OTA”) update will update the communication module software for the MBUX system on the affected vehicles. All customers will be mailed recall notification letters as required under federal regulations. For vehicles with a “Mercedes Me” subscription service, the software update will be performed OTA and so a dealer visit is not required.

The initial information that MBAG received from these reports was general in nature and did not point to any particular reason for the anomaly. MBAG proceeded to obtain a vehicle from the field for additional analysis in late summer of 2020. In cooperation with the MBUX system supplier, MBAG conducted an analysis of the vehicle throughout autumn of 2020. During the course of the testing, MBAG became aware of other reports from the field that indicated a possible issue with the performance of the MBUX system and rearview camera display. In these instances, customers reported a brief interruption of the rearview image after which it would immediately reappear. In the winter of 2020 and into 2021 MBAG worked to identify the conditions that appeared to affect the performance of the MBUX system under these two potential failure mechanisms. These aspects were further considered including whether they were related issues and any influence on each other. MBAG’s investigation revealed that the MBUX system may not initialize as intended depending on a specific combination of conditions such as component tolerances and temperatures. If those conditions were to occur, the rearview camera image might not be displayed. Further, through the investigation it was found that there is a possibility that an ongoing writing operation on the hard drive of the MBUX multimedia system could be interrupted during the “shut down” phase of the system. If this were to occur, the unprocessed data could be stored on the hard drive and the next time the MBUX system was initiated, while the system would restart as intended, it then could reboot itself approximately 50 seconds after system initiation.

Part 573 Safety Recall Report 21V-354 Page 17 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Either an authorized Mercedes-Benz dealer or an over-the-air (“OTA”) update will update the communication module software for the MBUX system on the affected vehicles. All customers will be mailed recall notification letters as required under federal regulations. For vehicles with a “Mercedes Me” subscription service, the software update will be performed OTA and so a dealer visit is not required. For vehicles without a Mercedes Me subscription service, the notification letter will advise the customer that they may opt out of the OTA update and visit an authorized Mercedes-Benz dealer to have the update performed. If the customer does not opt out within the specified period, the update will be performed OTA with the vehicle thereafter. Depending on conditions such as network coverage and consistency of the data connection, if the OTA update cannot be successfully completed, the customer will be notified and advised to visit an authorized dealer to have the update performed. Customers who subscribe to the Mercedes Me service may check the status of the update through the associated website and/or through the Mercedes Me App. If the vehicle is subscribed to the Mercedes Me Connect services, the current status of the remote software update will be listed on the Mercedes Me connect webpage under “Software Update”. Further information regarding software updates can be found in the Operator’s Manual.
